Japan and Microsoft do not get along when it comes to the Xbox video game console. That said, the company is looking to release its next-gen video game console later this year. September 4th has been marked in calendars and should you reside in the region, it won't be long until you'll be bale to pick an Xbox One up.
The only problem with the launch would be an almost 10 month gap between then official console launch in the US and other markets. There's still no word on pricing yet, but with E3 coming up soon, we can't imagine it being withheld for much longer. Be sure to monitor this space this year for more details on the Japan launch.
